Hello,

I was trying to convert a raspberry pi 4 (Raspberry Pi 02 lite 32bit) to mender. The conversion errors out with:

mount: /mender-convert/work/rootfs: wrong fs type, bad option, bad superblock on /dev/loop5, missing codepage or helper program, or other error.

I created the golden image as dd from

Disk: /dev/disk2	geometry: 7764/255/63 [124735488 sectors]
Signature: 0xAA55

Please advise.

Thanks & very best!

I would start by looking at the image you’ve extracted. Can you get it to mount locally?

@oleorhagen not sure how to mount it locally, but if I flash it onto an SD card using RPI imager, the PI is running fine.

Hmm, that is interesting.

You can mount the filesystem with the mount command, if you’re on linux. And then give it the right offset for the partition you want to mount.
